WebTo find the derivative of the given function, we will use the four-step process. Step 1: Compute f (x + h) and expand the expression. f (x) = 7x2 + 4x f (x + h) = 7 (x + h)2 + 4 (x + h) = 7 x2 + xh + h2 + 4 (x + h) = 7x2 + xh + 7h2 + 4x + 4h None of the terms in the expanded expression can be combined. Therefore, f (x + h) is as follows. WebGraph of the function intersects the axis X at f = 0 so we need to solve the equation: $$\left(\frac{1}{10} - \sin{\left(x \right)}\right) \cos{\left(x \right)} = 0$$ Solve this … WebSo x cos(y/x) is homogeneous, with degree of 1. Notice that (y/x) is "safe" because (zy/zx) cancels back to (y/x) ... Homogeneous applies to functions like f(x), f(x, y, z) etc. It is a … d way foods inc rei miyamoto
